Subsequent clinical course of the patient. In the case, proteinuria was successfully controlled for 6 months with corticosteroid monotherapy after discharge from our hospital. During the process of tapering prednisolone, serum IgG titer began to increase, and polyclonal gammopathy appeared. The patient was referred to another hospital for induction of anti-IL-6 therapy, tocilizumab. The disease markers of MCD such as serum IL-6 and plasma vascular endothelial growth factor were not examined.
